I just learned jquery, and what I wrote may not be correct, but it can be verified normally, and I will share it for your reference.

<html xmlns="http://www.w3.org/1999/xhtml">
<head><title>
</title>
<scrip去掉t src="scrip去掉ts/jquery-1.4.1.js" type="text/javascrip去掉t"></scrip去掉t>
<scrip去掉t type="text/javascrip去掉t">
$().ready(
function () {
$("#txtage").blur(
function () {
if (isNaN($("#txtage").val())) {
$("#labage").text("请输入整数!");
} else {
if ($("#txtage").val() > 99 || $("#txtage").val() < 0) {
$("#labage").text("请输入0-99之间!");
} else {
$("#labage").text("");
}
}
}
);
}
);
</scrip去掉t>
</head>
<body>
<form method="post" action="WebForm1.aspx" id="form1">
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwULLTE2MTY2ODcyMjlkZJWeBwsoKPQopHcY1RhEXRn5LJTG45ip0VWYP9uWZTuh" />
</div>
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATEGENERATOR" id="__VIEWSTATEGENERATOR" value="C687F31A" />
</div>
<div>
请输入年龄:<input id="txtage" type="text" /><label id="labage"></label>
</div>
</form>
</body>
</html>
